Frontiers in the Growth of Complex Oxide Thin Films: Past, Present, and Future of Hybrid MBE.

Driven by an ever-expanding interest in new material systems with new functionality, the growth of atomic-scale electronic materials by molecular beam epitaxy (MBE) has evolved continuously since the 1950s. Here, a new MBE technique called hybrid-MBE (hMBE) is reviewed that has been proven a powerful approach for tackling the challenge of growing high-quality, multicomponent complex oxides, specifically the ABO₃ perovskites. The goal of this work is to (1) discuss the development of hMBE in a historical context, (2) review the advantageous surface kinetics and chemistry that enable the selfregulated growth of ABO₃ perovskites, (3) layout the key components and technical challenges associated with hMBE, (4) review the status of the field and the materials that have been successfully grown by hMBE which demonstrate its general applicability, and (5) discuss the future of hMBE in regards to technical innovations and expansion into new material classes, which are aimed at expanding into industrial realm and at tackling new scientific endeavors.
